ADG431BNZ Precision Analog Switch by Analog Devices Inc.

The ADG431BNZ is a high-performance monolithic analog switch from Analog Devices Inc., renowned for its precision and reliability in various applications. This component is part of a series that utilizes advanced silicon-oxide-nitride-oxide-silicon (SONOS) technology to provide superior switch characteristics. It is a perfect solution for systems requiring an accurate signal routing function, such as data acquisition systems, communication systems, and medical equipment.

With its low power dissipation and single supply operation ranging from +10 V to +30 V or dual supplies of ±5 V to ±15 V, the ADG431BNZ ensures versatility in different circuit configurations. The device features low on resistance (R<sub>ON) of typically 45 Ω, which remains flat over the full analog signal range, ensuring excellent linearity and minimal signal distortion.

The ADG431BNZ offers a high degree of switch off isolation and low leakage currents, which are critical parameters for precision applications. The off isolation is typically -60 dB at 1 MHz, and the leakage currents are in the picoampere range, making it an excellent choice for sensitive analog signal handling. Furthermore, the device exhibits fast switching times—typically 150 ns for t<sub>ON and 100 ns for t<sub>OFF—which is beneficial for applications that require rapid signal switching.

Encased in a robust 16-pin PDIP (Plastic Dual In-line Package), the ADG431BNZ is designed for easy integration into a wide variety of circuit boards. The package is engineered for optimal thermal performance and long-term durability. Additionally, the ADG431BNZ is TTL/CMOS compatible, allowing for straightforward interfacing with digital logic components.

With its comprehensive set of features, the ADG431BNZ is a top choice for designers looking to improve their system performance with a reliable and precise analog switch. Whether used in test equipment, sample-and-hold circuits, or audio signal routing, the ADG431BNZ delivers consistent, high-quality performance that engineers can trust.
